Abstract

PURPOSE:To automatically start a batch job at midnight by attaining a constitution where the monitor time and the executing time are set by a system input part and the designated time is detected by a monitor part for execution of an automatic submitting operation of the batch job. CONSTITUTION:When a monitor part 2 is started to carry out a monitor program, the control data on the starting time of a batch job is read out of a system input part 1. Then a clocking part 6 checks the present time and a comparison part 5 compares the present time with the designated start time after this start time is recognized in the part 2. At the designated start time, the control data including a JCL (job control language) data set name is read out the part 1. Then the JCL data to be submitted are read from a job control data part 3. In such a constitution, the batch job can be automatically started at midnight.

[Industrial application field]

The present invention relates to a batch job submission method, and more specifically, it is used for testing computer systems or developing programs for maintenance.
The present invention relates to a batch job submission method that makes effective use of a CPU and allows batch zip to be reliably executed without any troublesome work.

[Conventional technology]

2. Description of the Related Art Conventionally, computers have been used to perform various tasks in developing test programs for computer systems, maintenance programs, and the like.

In this work, during the daytime, TSS work is mainly performed between the CPU and the terminal device, and if the computer is operated with the CPU relatively idle, the TSS work during the daytime
Batch jobs were submitted at night to avoid using the development resources used during S operations as batch jobs.

[Problem to be solved by the invention]

The above-mentioned conventional devices had the following drawbacks.

(1) When a computer user attempts to start a batch job, he or she must wait until the time when the batch job is to be started, which places a heavy burden on the user.

(2) When a batch job is placed in an execution pending state and held in a spool in advance, and an attempt is made to start it by an operator command, the job may not be executed successfully due to the hassle of contacting the operator or due to errors caused by operator intervention.

The present invention solves these conventional drawbacks by automatically starting batch jobs that have been submitted in advance, thereby eliminating troublesome work and making effective use of the CPU. The purpose is to enable batch job execution.

[Means to solve the problem]

In order to achieve the above object, the present invention is as follows.

FIG. 1 is a diagram showing the principle of a batch job submission method according to the present invention.

First, the monitoring unit 2 is activated in advance. When the monitoring section 2 is started and the monitoring program starts executing, control data of the time at which the batch job should be started is read from the system human resources section I.

In the monitoring section 2, when the specified time activation is recognized from the control data, the clock section 6 checks the current time, and the comparison section 5 compares the current time with the specified activation time.

In this way, monitoring of the designated start time is continued at regular intervals.

Then, when the specified startup time is reached, the system human power section 1
From J CL (job control language
age) Read the control data containing the data set name, and read the JCL data from the job control data section 3 containing the JCL to be submitted.

The monitoring unit 2 reads the JC data from the job control data unit 3.
Output the L data to the internal reader 4.

This will launch and execute the batch job.

The above steps are repeated until the job control data section 3 is no longer specified by the system human resources section 1.

[Effect]

With the above configuration, it is possible to automatically start a batch job by specifying a time, such as starting a batch job late at night, which conventionally could only be done manually.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. Second
The figure is a block diagram of a batch job submission method that is an embodiment of the present invention, Figure 3 is an operation flowchart, Figure 4 is an example of a control button in the system input section, and Figure 5 is a JCL data set in the job control data section. It is a figure showing an example.

1 is a system input section (SySiN data set), 2 is a monitoring section, and includes a clock section 6 and a comparison section 5.

3 is a job control data section (JCL data set), 4 is an internal league, 7 is a printer (SySPRiNT data set), and 8 is a spool.

First, start the monitoring program.

The monitoring program is Printerf's rs3FsPRiNT.
Dataset” and then System Human Resources Department 1
rSySiN data set" and read l records of control data.

The control data is as shown in FIG. 4, for example. The first data is 'SUBM i T, DATE
=yy, mm,, dd%TiME=hh.

mm, SSJ, and specify the time to submit.

2 The first data is rDSN=Q2892, COM,
JCLI (¥AAA)J, and specify the JCL to be submitted.

The next number 3 also specifies the JCL to be submitted, and the JCL to be submitted is specified in the same manner.

As mentioned above, the control data includes rSUBMITJ for specifying the startup time of the batch job and fDSN=J for specifying the dataset name in which the JCL to be submitted is stored. be.

The monitoring program recognizes the control data and selects “SUBMi”.
T, DATE=yy, mm, dd, TiME=h h,
mm, s SJ data is read.

Since this control data is 'SUBMiT', the monitoring section 2 reads the current time from the timer section 6, and the comparison section 5 reads the current time.
The specified time is compared with the current time.

As a result, if the specified startup time has not arrived, rs7si
NJ is closed and rWAiTj processing begins.

The above operation is repeated until the specified time is reached, and when the specified startup time is reached, the internal reader is opened to submit the JCL data.Then, the monitoring program of the monitoring section 2 executes the rsysiN of the system input section 1. Read the specification information of the JCL data set name to be activated from ``Dataset'' in one record.

Next, open the JCL data set to be started in the job control data section 3, read the data, and output it to the internal reader until the end (EOF)
continue.

JCL dataset is EOF (END 0FFiL
When E) is detected, the JCL dataset is closed and 1
One submission is completed.

FIG. 5 is a diagram showing an example of the above JCL data set, in which an arbitrary number of arbitrary jobs are set.

Such a job, that is, the JC of the job side control data section 3
The L data set is output to the internal reader 4, and further sent to the spool 8, where a batch job is executed.

This is repeated until the 5ySiN data set in the system input section 1 no longer specifies the JCL data to be activated.
``When EOFJ is detected, internal reader 4, rsysiN dataset'' from 5ySiN dataset,
'Close each SySPRiNT data set J.

This means that all batch jobs have ended, and the monitoring program disappears.

Using the method described above, multiple batch jobs are started and executed at the specified time.

〔Effect of the invention〕

As explained above, the present invention has the following effects.

(1) If you try to request batch processing at night,
Since the submission can be made in advance, there is no need for the person in question to be present at that time.

(2) By avoiding daytime hours and executing the job as a job at night, there is no interference with TSS users accessing the same data set, which improves CPU usage efficiency.

(3) Since the desired batch job can be started automatically, there is no need to make mistakes due to operator intervention as in the past, and batch jobs can be executed reliably.
